Barcelona continued their summer spree yesterday by agreeing a deal to take the Monaco midfielder Yaya Touré to Camp Nou for a reported €10m (£6.7m). The Ivory Coast international, 24, the younger brother of Arsenal's Kolo Touré, will undergo a medical today before being introduced as a Barcelona player, a day after Thierry Henry joined the club.

Touré played in all Ivory Coast's matches in the World Cup last summer and has wide experience in European football, having previously played for Beveren in Belgium, Metalurg Donetsk in Ukraine and Olympiakos in Greece.

One player not on the move this summer is David Trezeguet. The France striker made an about-turn yesterday and renewed his contract at newly promoted Juventus. "I am proud to link my name with Juventus for another four seasons," said the 29-year-old, who had previously said the Italian club's initial contract offer made him feel unloved.

Talks between Birmingham City's owners and the billionaire Hong Kong-based businessman Carson Yeung were continuing last night, with David Gold's new willingness to sell increasing the prospect of a takeover deal. Birmingham's chairman had previously described himself as "not a willing seller" but it is understood that his stance has changed.

With Birmingham's co-owner David Sullivan known to be disillusioned at St Andrew's, Gold's switched position means that the path has been cleared for Yeung to step up his interest. Yeung has completed the process of due diligence and both parties are in agreement on a £50m valuation. Discussions have gathered momentum since Sunday when Yeung, who is being advised by Keith Harris, the executive chairman of Seymour Pierce Investment Bank, arrived in London.

The Preston North End striker David Nugent's future remains uncertain after he had talks with Sunderland. He is understood to have met officials on Friday after two clubs were given permission to talk to him, but Preston's chairman, Derek Shaw, admitted: "We are not sure if he met the other club. David has now gone on holiday for a week and we are hoping to get an update from his representative."

West Ham, Derby, Blackburn and Birmingham have also been linked with the 22-year-old England forward. Sunderland appeared to get in first when they spoke to him amid claims that he had told friends he had already decided to sign for them. Their manager, Roy Keane, has targeted several front men, including Villarreal's Diego Forlán. He is also said to be interested in Manchester United's Alan Smith but Middlesbrough are understood to have formalised their interest in the 26-year-old former Leeds player.

The Hearts goalkeeper Craig Gordon is also interesting Keane after Jussi Jaaskelainen's decision to see out the final year of his contract at Bolton. Hibernian have signed the Newcastle winger Alan O'Brien on a three-year contract after he agreed personal terms. The clubs have yet to agree a compensation fee for the 22-year-old.
